Hierarchical Set Definition by Q-Analysis, Part II. Traffic on the Hierarchical Backcloth

Article Abstract:

The second part of a discussion of hierarchial set aggregation and simplicial complexes is presented. It focuses on traffic on hierarchial backcloth of simplicial complexes. The combinatorial structure of traffic is called supertraffic and is represented by composite pattern polynomials. Television program information is used to illustrate the development of concepts. Polynomial forces and t-u-forces are investigated. Familiarity with the first part of the discussion is assumed.
